Yes, remnants of the heavy rainfall have left Death Valley with a lake that is multiple miles long and about 2 miles wide, as of January 24, 2024.
Death Valley's unique geography, characterized as an internal basin, prevents water from draining out to sea. This means that significant rainfall events, such as the one that occurred prior to January 2024, can result in the temporary formation of a lake. While the lake is not a permanent fixture, it demonstrates the impact of extreme weather events on this desert landscape. It's important to note that while the valley is currently experiencing this phenomenon, the water level will recede over time due to evaporation and seepage.
